Kevin Carey explains the issues with using a tuition tax credit system to fund school vouchers in the New York Times:
Steve Yarbrough is one of the most powerful men in Arizona. As president of the State Senate, he has promoted a range of conservative policies, including a tuition tax credit system that provides over $100 million per year to finance vouchers for private schools.
In his speech to Congress this week, President Trump singled out a young woman who attended private school using a tax credit-financed voucher. The president urged Congress to pass legislation that would provide similar benefits to millions of students.
But Mr. Yarbrough is not just a champion of tax credit vouchers. He also profits from them personally. The story of how that happened raises questions about President Trump’s campaign promise to spend $20 billion to increase school choice. There’s a strong chance that he’ll do that through tax credit vouchers — a mechanism that Betsy DeVos actively campaigned for before she became Mr. Trump’s education secretary.
